. To all whom it may-concern:

' inafter set forth I, in Fig. 1.

Be it known that I, CARL H. BISSELL, of Syracuse, in the county ofyOnondaga and State of New York, have invented a new and useful Pipe Connection, of which the following, is aspecification.

This invention has for its objectthe production of a pipe connection particularly designed to be used in connection with electrical conduits and service boxes used inthe railway service, and the invention consists in the combinations and constructions and claimed.-

In describing this invention,- reference is had to the accompanying drawings in which L like characters designate corresponding .parts in allthe views.

Figures 1 and 2 are respectively an end elevation and sectional fragmentary view of one form of car service box embodying my invention, the conduit or pipe being shown in section in. Fig. 1.

Fig. 3 is an elevation of the threaded ring of the pipe connection.

Fig. 4 is a plan of the conduit box shown 7 comprises a split This pipe connection clamp including two clamping members, one

of which is movable relatively to the other, the clamping members confining a passage or opening for receiving the conduit or pipe, and a nut threadingon the portion of the pipe in the passage oropening of the clamp and designed to be held clamp after the movable clamping member is tightened into its operative position. The nut is split, and the threads of the pipe and the nut constitute interlocking means extendin circumferentially 0f the pipe so that when t e contractile ring is contracted onto the pipe, a tight joint ring, the pipe and the clamping member, by reason of this interlocking means.

The clamping members are here shown as associated with the service box of a railway car, and 1 and 2 are the clamping members, the member 1v being usually fixed to the box and the member 2 being removable and being clamped into its operative position inany suitable manner as by screws 3. The clamping members 1: and 2 confine a cylindrical opening 4: for receiving the pipe or conduit 5 or the threaded portion thereof and said 0 ening is of greater diameter than the threa ed surface of the pipe. The

clamping parts 1 and 2 are separable along Specification of Letters Patent.

a plane extending in a direction lengthwise of the opening 4 and clamped toward each other onto the pipe in a direction at an angle to the axis of the pipe.

6 is the nut signed to be threaded on the pipe 5 before.

the end thereof is inserted in the opening 4, the ring being preferably partly inserted in an annular groove 7 formed in the inner faces of the clamping members 1 and 2. This ring is usually expansible and contracshown as split, as seen in Fig. 3 and as being substantially rounding, semi-circular or are shape in cross-section and fits into the groove 7 which is are shaped in cross-section.

In operation, after the ring 6 has been turned on the pipe 5, the pipe is laid into the semi circular opening of the fixed clamping member 1 with the ring fitted into the portion of the groove 7 in the fixed clamping member, the movable clamping member is then placed into position with its section of the groove 7 fittingthe ring, and the movable clamping member is then tightened by turning the screws 3. This pipe connection is advantageous in that no turning of the pipe is necessary and the pipe can be always tightly fitted to, the service box. It is of particular advantage when the pipe has an elbow andthere is not a suificient space to turn the pipe sufiiciently to tighten the same What I claim is 1. The -combination with a ireaded pipe,

provided with opposing clamping members having a pipe receiving opening into which the pipe with the nut thereon is placed with the nut within said opening, and means for clamping one member toward the other in a direction at a right angle to the pipe and the nut, substantially as and for the-purpOse described.

2. The combination with a threaded pipe,

in the form of a ring deof a nut threading onthe pipe, and a body of a nut threading on the pipe, and a body provided with clamping members having a pipe receiving opemng and an internal annular groove for receiving the nut, the line of division between the clamping members of the axis of the opening, and means for clamping one member toward the other onto the pipe and,the

nut, substantially as and for the purpose specified.

1 3'. The combination with a threaded pipe, I

ceiving the pipe and the nut thereon and including opposing members, the memhers being separated in a direction lengthwise oi the axis of the opening, and means for clamping one of the members toward and from the other in a direction at an angle to the axis or said opening, substantially as and tor the purpose set forth.

4. The combination with a threaded pipe, of an e'rpansihle and contractile split nut threading on the pipe, and a body provided with a clamp having a pipe opening for receiving the pipe, and an internal annular groove around the opening for receiving the nut, the clamp including opposing members, the members being separated in a direction lengthwise of the axis oi the opening, and means for clamping one oi" the members toward and rrom the other in a direction at an angle to the axis oi said opening, substantially as and for the purpose described.

5, The combination with a threaded pipe, of an expansihle and contractile split nut semicircular in cross section threading on the pipe, and'a body provided with a clamp having a pipe opening for receiving the pipe, ands-n internal annular groove around the opening for receiving the nut, the groove fitting the nut, said clamp including members separated in a direction lengthwise oi the axis of theopening and the groove, and means for clamping one of the memhers to ward and from the other in a direction at an angle to the axis of said opening, substantially as and for the purpose specified.

6. The comhination with a threaded pipe, of enoansihle contractile ring inroaden pipe, the hotly with split clamp having a pipe receiving opening,

the clamp including members separated in a direction lengthwise or the axis of the openin the clamp being also formed with an internal annular groove around the opening for receiving the-ring,-the ring being semicircular in cross-section, and the groove being semi-ciroular in cross section, and

means for clamping said members toward each other in a direction at an angle to the axis of the pipe opening, substantially as and for the purpose described.

8. The combination with a pipe and a body to which the pipe is connected; of a pipe joint between the pipe and the body comprising a contractile, split, internally-' threaded ring threading on the pipe, and means associated with the body for contracting the ring on the pipe without turning the ring, substantially as and for the purpose specified.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses at Syracuse, in the county of Onondaga, in the State of New York, this 16th day of May, 19%.
